Well for those that may remember that My First 05 Eddie Ex was bought back by Ford because the Dead Squirel and the Squirel nest that was between my radiator and condensor caused the truck to overheat... and the squirel ate through the fan wires.......
Ford Made me a new one that I just got two weeks ago.
I took my first long trip in it and at 70mph and higher the truck starts making a strange hum/groan from the drive train. The faster you go, the louder it gets... and no turning up the radio doesnt make it go away... because you can still feel the vibration. I ran it up to 90, and put the truck in neutral... it went away... so therefore it cant be tires.
The hum comes at the point when you just feather the throttle between gas and deceleration. It gets quite bad at 80.
I called my dealer and took it to them.. the tech went with me for a ride... we ran it up to 80 and he said... damn... what the hell is that noise!?!?!? I said... hey your the tech.. you tell me..... he said... wow.. never heard that before....  Ok... so here we go again.
After two days the dealer has said that the driveline angle is in spec, and the u joints are ok... they think its the pinion gear...... so that is what they are going to replace. could make sense.. but I dont want to get in the habbit of just shotgunning parts.
Any of you experts have any ideas??

If it were the pinion then I would think the noise would continue in neutral.

Your suspension, driveshaft, pinion angles, rearend, etc. are all fine if the noise/vibration goes away with the X in neutral.
I would point this out to them and have them start looking at the tranny. For starters, they will probably check the fluid, maybe even drop the pan, put new fluid in, run a vehicle diagnostic, etc. If the vibration is still there and no error codes are present, it's going to be a mechanical issue. The torque converter seems to always be the cause of vibration whenever a vibration gets narrowed down to the transmission. Not being familiar with the newer 5-speed autos, this is pure speculation.
If you put it into neutral, then you immediately eliminate any suspect parts from the driveshaft through the rearend, axles, wheels, and tires. Once the transmission is engaged, the vibration is apparent. Seems pretty obvious to me that the dealership needs to go through the trans with a fine-tooth comb.
Good luck and sorry to hear about this problem in your 2nd X.

Ok so here is the frustrated update:
The dealer had a a noise vibration monitor hooked to the rear Dif..... they worked with Fords coveted Engineers and now have replaced the pinion bearing and pinon gear.
Guess what.... they took it for a drive and wow... they have the same problem.... GOD you have to love Ford!!!
What a joke..... less than 1000 miles on a brand new truck and what junk.
So ... now the dealer doesnt have a clue what to do, and Ford is sending out some young engineer to solve the problem..... I think engineering is what got us here.
Anyway.... wouldnt it make sense since they say the noise is comming from the rear dif. to replace the whole axle on the truck?
ANYONE OUT THERE HAVE ANY IDEAS THAT I CAN HELP THE DEALER WITH?
BEFORE I DECIDE TO DRIVE THIS TRUCK THROUGH THE FRONT WINDOW OF DEARBORNS HEADQUARTERS.

I thought the noise went away when you shifted to neutral?
If it's a differnetial problem, they can just swap out parts. An entirely new rear axle costs more than new ring and/or pinion gears. Not to mentin the labor of swapping the rearend, brakes, brake lines, etc. I don't blame them for their methods, but I think you should point out the fact that the vibration goes away when you shift into neutral. They may be barking up the wrong tree by looking at the rearend -- what you describe sounds like a transmission issue.

Well, that is what I thought too ( about the noise disappearing when you shift it into N) However they said they hooked up a NVH gizmo to the rear dif...and then indicated that the noise was for sure coming from it.
Thoughts?

Since there's more than just a pinion in the rearend, it could be the ring gear, the limited slip, carrier bearings, etc. They will probably just rebuild the rearend as a next step. Seems like a very odd problem to have with a new vehicle. The rearend doesn't have anything new to it, so hopefully it's just a defective part from their supplier or the factory.
Do let us know what they find, I'm interested to hear what it turns out to be.

Ok, here is the latest latest update:
Ford engineers came out.... scratched their collective heads, and have authorised the dealership to procure and replace the entire rear end and axle. IT is supposed to be in tomorrow.
Let's hope that takes care of the problem!!!! I am not to keen on having my brand new truck getting brand new parts....
What do you think? Should I tell Ford to keep it?

Since the design on the rearends hasn't changed, the one you have installed in your X must have some factory defect. Seriously, the axles are the last things to really have problems on these (and Superduty's, for that matter). Talk about a tried and true design. I would not worry about it if the vibration disappears with the new rearend. You have many happy miles ahead of you.

Well.. here is the latest.... only 900 miles and this thing has been in the shop for 2 1/2 weeks now.
Ford has not replaced the entire rear axle, and guess what...the problem is still there. 
So.. according to Ford, there was a TSB that came out the third week of Sept this year for 2003 and later Diesel trucks that exhibit a similar problem. According to Ford they are to replace the bracket support for the turbo. Well they did.... and guess what.... the problem is still there.
So, now they are waiting for another engineer to come out and take a look at it. God knows when that will happen. Hell by the time they get done I will have an entire new drivetrain. What a POS!!!!!
I think I should have kept my hummer.... at least when that broke, we knew what to fix!!!!!!
